Common Lisp library for reading and writing data-frames
Data Frame I/O
Table of Contents
About the Project
A data frame isn't much use if you have to type all the data in by hand. This system provides I/O functions to read data sets from delimited (CSV, TSV, etc.) files. File may be either on local disk or accessible from network locations.
To get a local copy up and running follow these steps:
Getting the source
To make the system accessible to ASDF (a build facility, similar to
make in the C world), clone the repository in a directory ASDF knows about. By default the
common-lisp directory in your home directory is known. Create this if it doesn't already exist and then:
- Clone the repository
cd ~/common-lisp && \ git clone https://github.com/Lisp-Stat/data-frame.git && \ git clone https://github.com/Lisp-Stat/dfio.git
- Reset the ASDF source-registry to find the new system (from the REPL)
- Load the system
If you have installed the slime ASDF extensions, you can invoke this with a comma (',') from the slime REPL.
(clpm-client:sync :sources "clpi") ;sources may vary
You need do this only once. After obtaining the dependencies, you can
load the system with
ASDF as described above without first syncing
Create a data frame from a file named
sg-weather.csv on the local disk:
(defparameter *df* (read-csv #P"LS:DATASETS;sg-weather.csv"))
For more examples, refer to the Documentation.
